1. Bulletins Topics
Sun announces the release of patches for SunOS 4.1.4 and 4.1.3_U1
containing the same version of sendmail included with SunOS 5.x:
V8.6.9 plus extensions. SunOS 4.1.4 and 4.1.3_U1 originally
included V5 sendmail.
Sun recommends that customers using sendmail on SunOS 4.1.4 and
4.1.3_U1 install the patches listed in section 4 below to take
advantage of security and other enhancements found in V8 sendmail.
2. Understanding What is Available
sendmail is a public domain utility based on SMTP, which provides
internetwork mail routing. SunOS 4.1.4 and 4.1.3_U1 originally
included version 5 of the public domain sendmail with Sun

Various security related improvements were made to subsequent versions
of the public domain sendmail. These improvements were included in the
version of sendmail that Sun provides with SunOS 5.x, V8.6.9; in addition,
Sun's version includes enhancements to address subsequently identified
security vulnerabilities. The patches listed in section 4 below provide
this same version of Sun sendmail for SunOS 4.1.4 and 4.1.3_U1 customers.
